A series of studies were conducted to determine how intestinal function in animals could be manipulated by exogenous administration of peptides. In all bird studies, epidermal growth factor (EGF) or peptide YY (PYY) was administered three days prior to hatching (US Patent #5,916…

Cereal stubble and straw are widely used as animal feeds for sheep in arid areas of Morocco. Their low protein concentration limit their intake and therefore their potential of production. A 10-wk wheat (Triticum aestivum L.) stubble grazing trial was conducted to study the effe…
An extensive literature review and comparative analysis of heat and moisture production (HP, MP) of various poultry types (layers, broilers, and turkeys) and their housing systems indicated that total heat production (THP, W/kg) has increased over the years by about 15 to 44% (1…
Two experiments were conducted to determine the effects of level of concentrate supplementation and ruminally undegraded protein on dry matter intake and milk production on Holstein cows in late (Exp1) and early (Exp2) lactation. In each experiments, eighth (8) Holstein cows wer…
Experiments were conducted to evaluate oligosaccharides (OS) and fish oil on gastrointestinal tract characteristics and metabolic profiles of humans, pigs, and rats. Experiment 1, thirty healthy human adult males were assigned to one of two enteral diets, a control (n = 10) and …
Genetic analysis was conducted on experimental and commercial turkey lines using molecular biological techniques to measure genetic parameters. Four experimental lines, eleven commercial lines, and wild turkeys were used in restriction fragment length polymorphism (RFLP) analysi…
A total of six experiments were conducted to evaluate the effects of supplementing specific nutrients including menhaden fish meal (MFM), spray-dried plasma (SDP), glutamine (GLN), glutamate (GLU), monosodium glutamate (MSG), nucleotides (NUC), and a hatchling supplement (Oasis)…
Sesbania sesban and Sesbania goetzei are leguminous trees that produce forage for ruminants in Africa. These grow in a wide range of environments and have a high concentration of protein (>20%) in the leaves. There is considerable interest in using Sesbania perennials, including…
There is a dearth of empirical evidence demonstrating the degree to which exercise increases dietary protein requirement of the horse relative to maintenance. Knowledge of protein digestibility in diets fed to exercising horses is also essential to meet the protein need of the a…
The research problem of the study was to determine if two low-cost “home-mix” duck feeds developed by the Development Service Center could produce equivalent egg production in Khaki Campbell ducks compared to a high-cost “commercial” duck feed. Results from this study could be u…
The calpain system is a critical protease system in protein accretion and animal muscle growth. The calpain cDNA's from pigs and cattle were cloned to study the roles of calpain in muscle growth in domestic animals. By using reverse transcriptase and polymerase chain reaction, p…
The free-ranging Sumatran Orang-utans (Pongo pygmaeus abelii) found within the Gunung Leuser National Park (GLNP), Aceh, Sumatra are known to participate in geophagic activities. Ex-captive juvenile orang-utans (Pongo pygmaeus pygmaeus) of the Wanariset Research Station, Sungai …
Birds have high metabolic rates, body temperatures, and plasma glucose concentrations yet physiologically age at a rate slower than comparably sized mammals. The antioxidant activity of uric acid was studied. Study 1 consisted of 18 female broilers consuming inosine or hypoxanth…
The first objective was to develop an accurate, robust and broadly applicable prediction model of feed consumption of dairy cows in early lactation, and then to compare it with the current NRC model. Among various functions, an exponential model was selected for its best fit to …
Meat and bone meal and poultry by-product meal are common by-product used in poultry rations. Unfortunately, the quality of meals varies greatly, making it difficult to precisely measure the nutrient availability. The variability of the above mentioned by-product meals has made …
This research was conducted in order to determine the effects of protein source in the supplement on growth of grazing Senepol and Charbray heifers. Supplements were formulated to provide most of the protein either from soybean meal and ethamol (SY-ET), soybean meal, fish meal a…
Increased prolactin (PRL) secretion by the anterior pituitary gland is responsible for expression of incubation behavior that results in ovarian regression and loss of egg production in turkey breeder hens. A cellular basis for the heightened PRL secretion in the turkey hen has …
The present research was performed to characterize immunoreactive (ir) pituitary cells in the equine species. Two experiments were performed to measure the prevalence of single- and double-hormone labeled gonadotropes, lactotropes, somatotropes, and mammosomatotropes. In Experim…
To examine the effects of fat composition and supplemental vitamin E (Vit E) and selenium (Se) on in vivo lipid peroxidation, diet-induced hypercholesterolemia, and glutathione (GSH) metabolism, male Syrian hamsters were fed for three weeks butter fat (BF-) or fish oil- (FO-)bas…
